Not sure where this belongs, sorry >.<
does anyone have any tips for how to last walking around all day at cons in heels? I barely managed it at expo the other week >.< (I am aware the heels are stupidly inappropriate footwear at cons but some costumes do have them, and I need them to make height also XD

It can be tempting to get the first shoes that match your cosplay, but it's well worth holding out for a comfy pair. Saying that I've worn my fair share of crippling cosplay shoes.

Top tips would be get them in a slightly lower heel than is accurate or try hidden platforms for slightly less pressure. After that it's careful management of sitting down time, barefoot/comfy place holder shoes time combined with squishy shoe pads you can get seemingly anywhere that sells tights and blister plasters.

Remember to wear your shoes around the house before the event to get an idea of where they may rub before hand and pad up accordingly

What I always do when I wear heels for cosplay is wear them around the hours for a few hours for a few days. This allows for the feet to get a little more used to the weight and also helps with practicing balance as I wasnt much of a heel wearer until recently.

Another thing worth mentioning is looking into the thickness/wideness of the heel. That really makes a difference and wider heels tend to feel safer, plus they are better for balance and feet are a little less hurty at the end.

The one piece of advice I would give for ANY sort of uncomfortable footwear is bring a extra pair of really comfy shoes. I take moments for that particually when leaving the convention area for food or partying and while sitting down for long periods I just slip them off.

Soaking the feet at the end of the day and giving them massages is really helpful to relieve the pain.

I'm one of those smug bitches who finds heels more comfortable than flats. The only shoes I can't wear are the ones with the doofy curved sole, or stupidly high platforms. As long as the ball of my foot is relatively low, the heel can be as high as it likes. I wear heels every day, and I used to HAVE to wear them as part of my work uniform. My top tip would be to wear the shoes around the house as much as possible and just let your feet get used to them, The most foolish thing you can do is wear them for the first time on the day you intend to cosplay!

I had this problem at last Expo, too. What I did was bring a pair of flat slip-on shoes and wear my cosplay heels just for photoshoots and when I had to go on stage for the MGS competition. Whenever I wanted to just generally get around I'd change to the sensible shoes. I just kept them in a plastic bag to keep the rest of my things clean and put them in the main bag I was carrying around throughout the day.

This is all really good advice ^_^ not sure why I haven't thought of using the padded things xD I usually wear thick heeled shoes and at expo I wore slim type ones... That could be the issue >.< I think the idea of the platforms.hidden platforms could help too... as i need to illusion of being taller more then the heels themselves, if that makes sense :s

If you have the time, heel training is seriously worthwhile. Like darkshines I wear heels or wedges all the time and I have done since I did my heel training at sixth form, which means when it comes to expo I can do 3 days of cosplay heels no problem.
If you start wearing low heels (or wedges are much easier for people used to flats) everyday just to do basic things like food shopping and housework you'll soon get used to them. The more you do it the easier it'll be to wear taller heels if you need to and the better you'll walk in them.
If you have a friend who wears them a lot observe how they walk, as often you'd have to adjust the way you walk a little to compensate.
Hope that helps.

In addition to all the great advice so far, also remember that as well as the muscles in your feet, your calves and thighs will be under different pressure than regular shoes. So bring some Deep Heat, and massage those legs!

Reiterating the ones i recommend after spending Sunday Expo in 5" heels:
1 - gel insoles/pads
2 - take breaks from standing as often as you can
3 - carry some spare flat shoes for travelling back to home/hotel at the end of the day (or for if it all gets too much)
